In case you missed it, Chance The Rapper made this announcement last night on Twitter: “Dear Chicago, I have something special for you this Saturday, not what you think it is.” The caption was followed with a link that directed followers to his website where tickets were on sale for an event of some sort called “Magnificent Coloring World.” The two-and-a-half-hour event takes place four times this Saturday, May 21 and total cost is $40 dollars. The later show costs $60, but beer is included in the ticket price. No details on what this is exactly, but check out the Instagram photo and tweets below.
